[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] In the description of this utility model, it should be understood that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.
[0028] The purpose of this invention is to provide a zipper release device and an automatic placket opening machine, which can effectively improve the zipper sewing accuracy and reduce the probability of producing defective products.
[0029] Please see Figure 1 and Figure 2 To achieve the above objectives, this utility model provides a zipper placement device, including a zipper placement plate 100 with a receiving groove 110. The receiving groove 110 includes a zipper tail clearance groove 111, a first zipper tooth groove 112, a first zipper head clearance position 113, a second zipper tooth groove 114, and a second zipper head clearance position 115, which are sequentially connected along the length direction of the zipper placement plate 100. The zipper tail clearance groove 111 is used to position the tail of the zipper, which is the bottom stop of the zipper. The zipper teeth are laid along the length direction of the zipper placement plate 100, and at least some of the teeth are engaged with the first zipper tooth groove 112, and the zipper head is located in the first zipper head clearance position 113 or the second zipper head clearance position 115.
[0030] The zipper placement plate 100 is provided with a receiving groove 110. By adapting the receiving groove 110 to the zipper, the accurate positioning of the zipper is achieved. Specifically, the receiving groove 110 includes a zipper tail clearance groove 111, a first zipper tooth groove 112, a first zipper head clearance position 113, a second zipper tooth groove 114, and a second zipper head clearance position 115, which are connected sequentially along the length of the zipper placement plate 100. After aligning the tail of the zipper with the zipper tail clearance groove 111, the zipper is laid along the length of the zipper placement plate 100 and at least part of the zipper teeth are engaged in the first zipper tooth groove 112 to fix the position of the zipper. The first zipper head clearance position 113 and the second zipper head clearance position 115 are used to accommodate the zipper head, making the zipper flat. This setting can achieve the positioning of the zipper for subsequent sewing, which can effectively improve the sewing accuracy of the zipper and reduce the probability of producing defective products.
[0031] It should be noted that the length directions of the first zipper tooth groove 112, the first zipper head clearance position 113, the second zipper tooth groove 114, and the second zipper head clearance position 115 are all consistent with the length direction of the zipper placement plate 100. Both the first zipper tooth groove 112 and the second zipper tooth groove 114 can engage the zipper teeth. When the zipper is relatively short, after aligning the tail of the zipper with the zipper tail clearance groove 111, the zipper teeth are engaged in the first zipper tooth groove. Within 112, the zipper pull is accommodated in the first zipper head clearance position 113. When the zipper is long, after aligning the tail of the zipper with the zipper tail clearance groove 111, the zipper teeth are inserted into the first zipper tooth groove 112 and the second zipper tooth groove 114, and the zipper pull is accommodated in the second zipper head clearance position 115. The zipper placement plate 100 can adapt to the fixing of zippers of different lengths according to actual needs, thereby improving the versatility of the zipper placement plate 100.
[0032] Understandably, the engagement between the first zipper tooth groove 112 and the zipper tooth is achieved by the zipper tooth engaging with the first zipper tooth groove 112, whereby the tooth has a certain outward tension and abuts against the inner walls on both sides of the first zipper tooth groove 112 to restrict the movement of the zipper. Similarly, the engagement between the second zipper tooth groove 114 and the zipper tooth is achieved by the zipper tooth engaging with the second zipper tooth groove 114, whereby the tooth has a certain outward tension and abuts against the inner walls on both sides of the second zipper tooth groove 114 to restrict the movement of the zipper.
[0033] In one possible implementation, the zipper placement plate 100 is further provided with a sewing clearance groove 120 adjacent to the receiving groove 110. The length direction of the sewing clearance groove 120 is consistent with the length direction of the zipper placement plate 100, and is used for the machine needle to sew the zipper placed on the zipper placement plate 100 onto the fabric. It is understood that the zipper has a strip of fabric for connecting the chain teeth. When the chain teeth of the zipper are engaged in the first zipper tooth slot 112, the strip of fabric connecting the chain teeth is located on one side of the chain teeth in the width direction of the zipper placement plate 100. By sewing the strip of fabric connecting the chain teeth to the fabric, the zipper is sewn to a preset position on the fabric. By providing the sewing clearance groove 120 on the zipper placement plate 100 for the machine needle to sew, the zipper placed on the zipper placement plate 100 can be mechanically sewn, which helps to improve sewing efficiency.
[0034] In one possible implementation, the zipper placement plate 100 includes a first side 130 and a second side 140 opposite each other in its width direction, a sewing clearance groove 120 and a receiving groove 110 located between the first side 130 and the second side 140, and a first zipper tooth groove 112 located between the sewing clearance groove 120 and the second side 140. The distance between the first zipper tooth groove 112 and the sewing clearance groove 120 in the width direction of the zipper placement plate 100 is equal to the distance between the first zipper tooth groove 112 and the second side 140 in the width direction of the zipper placement plate 100.
[0035] The sewing clearance groove 120 can be used to sew the fabric strip on one side of the zipper teeth of the zipper on the zipper placement plate 100. By making the distance between the sewing clearance groove 120 and the first zipper tooth slot 112 in the width direction of the zipper placement plate 100 equal to the distance between the first zipper tooth slot 112 and the second side 140 in the width direction of the zipper placement plate 100, the fabric strip on the other side of the zipper teeth of the zipper on the zipper placement plate 100 can be sewn on the second side 140. For example, the right front piece of fabric and the fabric strip located on one side of the zipper teeth can be sewn at the sewing clearance groove 120, and the left front piece of fabric and the fabric strip located on the other side of the zipper teeth can be sewn at the second side 140.
[0036] Please see Figure 3In one possible implementation, the zipper holder further includes a reinforcing plate 200. The reinforcing plate 200 has a first through hole 210 corresponding to the first zipper head clearance position 113 and a second through hole 220 corresponding to the second zipper head clearance position 115. The reinforcing plate 200 is connected to the bottom of the zipper placement plate 100 and is used to block the bottom of the zipper tail clearance groove 111, the first zipper tooth slot 112, and the second zipper tooth slot 114 to restrict the zipper from passing through the bottom of the receiving groove 110. The reinforcing plate 200, connected to the bottom of the zipper placement plate 100, effectively improves the structural strength of the zipper placement plate 100. Simultaneously, by providing the reinforcing plate 200, one side of the receiving groove 110 can be blocked, allowing the opening on the other side of the receiving groove 110 to be used for zipper insertion, preventing reverse installation. The first through hole 210 and the second through hole 220 prevent interference between the reinforcing plate 200 and the zipper pull.
[0037] In one possible implementation, the zipper placement plate 100 is provided with a first connecting hole 150, and the reinforcing plate 200 is provided with a second connecting hole 230 corresponding to the first connecting hole 150. A connector is connected to the corresponding first connecting hole 150 and second connecting hole 230 to fix the zipper placement plate 100 and the reinforcing plate 200 relatively. The first connecting hole 150 and the second connecting hole 230 can be threaded holes, and the connector can be a screw, facilitating the installation and removal of the zipper placement plate 100 and the reinforcing plate 200. Two sets of first connecting holes 150 are provided, with each set arranged sequentially along the length of the reinforcing plate 200. The number and position of the first connecting holes 150 and the second connecting holes 230 can be adjusted according to actual needs to achieve the aforementioned purpose.
[0038] In one possible implementation, the zipper placement plate 100 further includes a clearance surface 160. The clearance surface 160 is located at one end of the zipper placement plate 100 along its length direction near the zipper tail clearance groove 111. The clearance surface 160 can be configured such that its projection along the length direction of the zipper placement plate 100 overlaps with the projection of the inner wall of the zipper tail clearance groove 111 along the length direction of the zipper placement plate 100. The clearance surface 160 can be formed by cutting one end of the zipper placement plate 100 along its length direction near the zipper tail clearance groove 111, so that the fabric strip of the zipper is suspended, making it easier for the entire zipper to be removed from the zipper placement plate 100.
[0039] In one possible implementation, the zipper tail clearance groove 111 is provided with a guide slope 170. The guide slope 170 is located at one end of the zipper tail clearance groove 111 away from the first zipper tooth groove 112. The guide slope 170 is set at an angle to the length direction of the zipper placement plate 100, and is used to guide the tail of the zipper to move into the zipper tail clearance groove 111, so that the tail of the zipper can easily slide into the zipper tail clearance groove 111.
[0040] In one possible implementation, the zipper placement plate 100 further includes a connecting portion 180, which is located at one end of the zipper placement plate 100 away from the zipper tail clearance groove 111 in its own length direction. The connecting portion 180 is used to connect with a moving device to move the zipper placement plate 100 to a preset position. The moving device may include a power source and a transmission mechanism, which drive the zipper placement plate 100 to complete the flipping and translation to change the position of the zipper for subsequent sewing.
[0041] Based on the above, this application also provides an automatic placket opening machine, including a moving device and a zipper placement device. The moving device is connected to the base plate 300 and the zipper placement plate 100, and can drive the zipper placement plate 100 to move relative to the base plate 300.
[0042] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0043] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0044] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
